Ka palekana o ka pauka corundum keʻokeʻo i loko o ka poʻi lāʻau lapaʻau
E hele i loko o kekahi mea lapaʻauponi anahale hana a hiki iā ʻoe ke lohe i ke kani haʻahaʻa o ka mīkini. Ke hana ikaika nei ka poʻe paʻahana i nā lole pale lepo, me nā pūlima ʻokiʻoki, nā prostheses hui, a me nā hana niho niho e ʻalohi anuanu i ko lākou mau lima - ʻaʻole hiki i kēia mau mea mālama ola ke pale i kahi kaʻina hana nui ma mua o ka haʻalele ʻana i ka hale hana: polishing. A ʻo ka pauka corundum keʻokeʻo ʻo ia ka "lima kilokilo" pono i kēia kaʻina hana. Eia naʻe, i nā makahiki i hala iho nei, me ka ʻike ʻana o kekahi mau hihia o ka pneumoconiosis o nā limahana, ua hoʻomaka ka ʻoihana e nānā hou i ka palekana o kēia pauka keʻokeʻo.
1. No ke aha e pono ai ke poni i na mea lapaau?
No nā huahana "make" e like me nā lāʻau lapaʻau a me nā implants orthopedic, ʻaʻole ʻo ka hoʻopau ʻana i ka ʻili he pilikia aesthetic, akā he laina ola-a-make. Hiki i ka micron-size burr ke hoʻopōʻino i ka ʻiʻo a i ʻole ka ulu ʻana o ka bacteria.ʻO ka micropowder corundum keʻokeʻo(mea nui α-Al₂O₃) loaʻa ka "mana paʻakikī" o 9.0 ma ka pālākiō paʻakikī Mohs. Hiki iā ia ke ʻoki pono i nā burrs metala. I ka manawa like, ʻaʻole hoʻohaumia kona ʻano keʻokeʻo maʻemaʻe i ka ʻili o ka mea hana. He kūpono ia no nā mea lapaʻau e like me ka titanium alloy a me ke kila kila.
Ua ʻōlelo ʻoiaʻiʻo ʻo Engineer Li mai kekahi hale hana lako ma Dongguan: “Ua hoʻāʻo wau i nā mea abrasive ʻē aʻe ma mua, akā ua hoʻihoʻi ʻia ke koena pauka hao e nā mea kūʻai aku a i ʻole ka haʻahaʻa haʻahaʻa.Korundum keʻokeʻo ʻoki wikiwiki a maʻemaʻe hoʻi, a ua hoʻonui pololei ʻia ka huina hua e 12% - ʻaʻole e ʻae nā haukapila i nā prostheses hui me nā ʻōpala. ʻO ka mea nui, ʻaʻole hiki ke hoʻopili ʻia kona ʻano kemika me nā mea hana.
2. Nā pilikia palekana: ka ʻaoʻao ʻē aʻe o ka pauka keʻokeʻo
ʻOiai ʻo kēia pauka keʻokeʻo e lawe mai i nā pono kaʻina hana, hūnā pū kekahi i nā wahi pilikia ʻaʻole hiki ke mālama ʻia.
ʻO ka inhalation o ka lepo: ka helu ʻekahi "mea pepehi kanaka ʻike ʻole"
ʻO nā micropowders me ka nui o 0.5-20 microns he maʻalahi loa ke lana. Ua hōʻike ʻia ka ʻikepili mai kahi keʻena mālama a me ka mālama ʻana i ka hana ma 2023 i ka helu ʻana o ka pneumoconiosis ma waena o nā limahana i ʻike ʻia i nā kiʻekiʻe kiʻekiʻe o ka lepo corundum keʻokeʻo no ka manawa lōʻihi a hiki i 5.3%. 2. "I kēlā me kēia lā ma hope o ka hana, aia kahi papa o ka lehu keʻokeʻo i loko o ka mask, a ʻo ka sputum coughed he ʻano one," wahi a kahi poni i makemake ʻole e kapa ʻia. ʻO ka mea ʻoi aku ka paʻakikī, ʻo ka manawa incubation o ka pneumoconiosis hiki ke lōʻihi i nā makahiki he ʻumi. He maʻalahi nā hōʻailona mua akā hiki ke hōʻino i ka ʻiʻo māmā.
ʻO kaʻili a me nā maka: ke kumukūʻai o ka pilina pololei
ʻOi aku ka ʻeleʻele o ka micropowder a hiki ke hoʻoulu ʻia i ka ʻili a i ʻole ka ʻānai ʻana i ka wā e loaʻa ai ma ka ʻili; ke komo i loko o nā maka, hiki iā lākou ke ʻohi maʻalahi i ka ʻili. 3. Ua hōʻike ʻia kahi hōʻike ulia mai kahi hale hana OEM kaulana i ka makahiki 2024 ma muli o ka ʻelemakule o ka sila maka maka makaʻala, ua loaʻa i kahi mea hana i ka lepo i loko o kona mau maka i ka wā e hoʻololi ai i ka abrasive, ka hopena o ka ʻāʻī ʻana a me ka pani ʻana i ʻelua pule.
ʻO ke aka o ke koena kemika?
ʻOiai ʻo ka corundum keʻokeʻo he paʻa kemika, hiki i nā huahana haʻahaʻa ke loaʻa ka nui o nā metala kaumaha inā loaʻa iā lākou ka sodium kiʻekiʻe (Na₂O>0.3%) a ʻaʻole i ʻohi ʻia. 56. Ua ʻike ʻia kahi ʻoihana hoʻāʻo i ka 0.08% Fe₂O₃6 i loko o kahi pūʻulu corundum keʻokeʻo i kapa ʻia ʻo "māka lāʻau lapaʻau" - he mea kānalua ʻole kēia i kahi pilikia huna no nā stents naʻau e koi ana i ka biocompatibility.
3. Ka hoomalu pilikia: e hookomo i ka "pauda weliweli" i loko o ka hale
No ka mea ʻaʻole hiki ke hoʻololi piha ʻia, ʻo ka pale ʻana a me ka hoʻomalu ʻepekema ke ala wale nō. Ua ʻimi nā ʻoihana alakaʻi o ka ʻoihana i nā "loka palekana".
Manaʻo ʻenekinia: E pepehi i ka lepo ma ke kumu
Ke ulu nui nei ka ʻenehana puluni wai - ka hui ʻana i ka pauka micro me ka wai wai i loko o ka paʻi wili ʻana, hāʻule ka nui o ka lepo ma mua o 90%6. ʻO ka luna hoʻomalu o kahi hale hana prosthesis hui ma Shenzhen i hana i ka makemakika: "Ma hope o ka hoʻololi ʻana i ka wili pulu, ua hoʻolōʻihi ʻia ke kaʻina hoʻololi o ka kānana ea hou mai 1 pule a i 3 mau mahina. ʻO ka ʻōnaehana hoʻoheheʻe kūloko i hui pū ʻia me ka pākaukau hana ʻino ʻole hiki ke hoʻopili hou i ka lepo e pakele ana2.
Palekana pilikino: ka laina hope o ka pale
ʻO nā maka lepo N95, nā aniani pale i hoʻopaʻa ʻia, a me nā jumpsuits anti-static he mau mea maʻamau no nā limahana. Akā ʻo ka paʻakikī o ka hoʻokō ʻana aia i ka hoʻokō - ʻoi aku ka mahana o ka hale hana ma mua o 35 ℃ i ke kauwela, a wehe pinepine nā limahana i kā lākou mau maka. No kēia kumu, ua hoʻolauna kahi hale hana ma Suzhou i kahi respirator naʻauao me kahi micro fan, e noʻonoʻo ana i ka pale a me ka hanu, a ua hāʻule ka nui o ka hewa.
Hoʻonui i ka waiwai: hānau ʻia ka pauka micro palekana
ʻO ka hanauna hou o ka lāʻau lapaʻau haʻahaʻa-sodiumkeʻokeʻo corundum(Na₂O<0.1%) he emi ka haumia a ʻoi aku ka nui o ka hāʻawi ʻana i ka nui o nā ʻāpana ma o ka pickling hohonu a me ka hoʻokaʻawale ʻana i ka ea. 56. Ua hōʻike ka luna ʻenehana o kahi hui abrasive ma Henan Province i kahi hoʻokolohua hoʻohālikelike: 2.3μg/cm² o ke koena alumini i ʻike ʻia ma ka ʻili o ka mea kani ma hope o ka hoʻoliʻi ʻana me ka pauka micro maʻamau, ʻoiai ʻo ka huahana haʻahaʻa-sodium he 0.7μg/cm² wale nō, ma lalo o ka palena maʻamau ISO 10993.
ʻO ke kūlana okeʻokeʻo corundum micro paukama ke kahua o ka lāʻau lapaʻau polishing e noho paʻakikī e haʻalulu i ka wā pōkole. ʻAʻole naʻe kona palekana, akā he hakakā mau ma waena o ka ʻenehana waiwai, ka hoʻokele ʻenekinia a me ka hoʻokele kanaka. Ke hopu ʻia ka lepo manuahi hope loa i loko o ka hale hana, i ka wā i pau ʻole ai ka maʻemaʻe o ka ʻili o kēlā me kēia mea ʻoki i ke olakino o nā limahana - paʻa maoli mākou i ke kī o ka "polishing palekana". Ma hope o nā mea a pau, pono e hoʻomaka ka maʻemaʻe o ka lāʻau lapaʻau mai ka hana mua o ka hana ʻana.
